Travelers In The Night

Asteroid 2004 BL86 was discovered more than 10 years ago by the LINEAR program in New Mexico.Until recently, we knew asteroid 2004 BL86 only as a faint moving point of light in the night sky. Early in 2015 it came close to planet Earth. RADAR images obtained with the 230 foot wide NASA Deep Space Network show that it is about 1100 feet in diameter and has a small moon about 230 feet across.
